OALDERS ATTACHM ENT FOR DISINTEGRATORS.

:XEGIFICATION formingpart of Letters Patent No. 708,972, dated September 9, 1902. Application filed March 15,1902. Serial No. 98,431. (No modelthe art to which it appertains to make and use the same, reference being, had to the accompanying drawings, and to the figures of ref erence marked thereon, which form a part of this specification.

Our invention relates to an attachment for disintegrators or pulverizers such as are used in disintegrating clay, ores, or other substances; and the object is to provide an improved scraper to scrape the clogged particles from t-heinner surface of the casing while the machine is in operation, and thereby prevent serious damage resulting from the material hardening, which retards the operation of the machine andsometimes fractures the parts.

Another object is to provide the scraper with removable and adjustable scraper-teeth and arrange two or more scrapers on the rotary cages in such relation to each other that the teeth of each will travel in different paths,

and thus engage the entire inner surface of the casing.

For a further understanding of the merits and advantages of the invention reference is to be had to the following description and the accompanying drawings, in which- Figure 1 is a horizontal section through the casing of a disintegrator, showing the scrapers mounted on the rotary cages and the position the scrapers bear with relation to the casing. Fig. 2 is a perspective of the scraper detached. Fig. 3 is a perspective of the clamping-piece.

Fig. 4 is a perspective of a portion of the scraper, the teeth and the clamping-piece being removed. Fig. 5 is across-section on the line m w of Fig. 1.

Like numerals of reference indicate corresponding parts throughout the several views. Referring to the drawings, 1 designates the transverse shafts, mounted in journal-boxes 2 and carrying at their ends the rotary cages 3 and 4, which are confined within the casing 5. All these parts may be of the usual construction, and they form no part of the present invention.

Our improved scraper consists of a member 6 and a clamping-piece 7. The member 6 is provided at each end with ears 8 and apertures 8, through which the fastening-bolts 9 pass to engage the plates 10 on the side of the rim of one of the rotary cages. The cross-bar 11 of the member 6 is provided with transverse semicircular grooves 12 and transverse apertures 13, which pass through the bar between the semicircular grooves and at right angles thereto. This cross-bar l1 joins the ears 8 at their lower left-hand corner to provide a recess between the ears 8, in which the clamping-piece 7 is secured. The clampingpiece 7 is also provided with semicircular grooves 14 and transverse apertures 15, passing centrally through the same between the grooves and at right angles thereto, so that when the said clamping-piece is fitted in the recess between the ears its semicircular grooves and apertures will be inalinemeut with the grooves and apertures in the crossbar 11.

As will be seen, the grooves 12 and 14 form a circular aperture when the parts are secured together, and in these circular apertures are fitted a series of scraper-teeth 16, consisting of cylindrical metal bars. The clampingpiece is held in place by means of bolts 17, which pass through the alining apertures 13 and 15, and on the end of the bolt is a threaded nut 18, which when unscrewed will release the clamping-piece from the cross-bar 11 and allow the scraper-teeth 16 to be adjusted longitudinally. When the scraper-teeth have worn to such an extent that they cannot be adjusted any further, new ones may be inserted without detaching the scraper from the cages.

Two or more scrapers may be mounted on the rotary cage 3, as desired, and each may have as many teeth as are required to scrape the entire surface of the casing. We prefer to use only two scrapers and employ six teeth in one and five in the other, the teeth being alternately arranged and hearing such relation to each other that each will travel in a diiferent path, and thus scrape the entire inner surface of the casing. So it will be understood that the number of teeth is immaterial.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. A scraper of the class described consisting of two members one of which is secured to the periphery of the rotary cage, and the other secured to said first-mentioned member, and scraper-teeth clamped between the members.

2. A scraper for disintegrators consisting of a member 6 secured to the periphery of the outer cage and having a recess, a clamping member fitted in said recess, and adjustable scraper-teeth carried by said members.

3. In a disintegrator, the combination With the cages and a casing inclosing the same, of a scraper projecting beyond the periphery of the outer cage, and composed of a member havinga cross-bar provided with grooves,and a clamping member provided with grooves to aline with grooves in the cross bar, and scraper-teeth adjustably mounted in said grooves.

4. In a disintegrator, the combination with the cages and a casing inclosing the same, of a scraper consisting of a member 6 having a cross-bar and projecting ears at the end of said bar to form a recess therebetween, a clam ping member secured in said recess, and adjustable scraper-teeth clamped between the members.

5. In a disintegrator, the combination with the cages and the casing inclosing the same, of scrapers mounted on the periphery of the outer cage and each consisting of a fixed member and a removable clamping member, removable and adjustable scraper-teeth carried by the members and arranged in alternate relation to each other so that the teeth of each scraper Will travel in a different path to scrape the entire inner surface of the casing.

In testimony whereof we affix our signatures in presence of two witnesses.
